Resending in case my usual email provider is blocked. >From the looks of gcc 6.0, it appears that gnu_parallel STL is slated to become part of the release. Am I right in believing that gnu_parallel STL code is not simd vectorized? Will there be an option to change this? PR60117 may be related in that it is a case where simd reduction is avoided with OpenMP. It's still marked unconfirmed even though I see that a useful discussion was appended over a year ago. I am able to build and run trunk on cygwin64 by papering over the winnt.c bootstrap failures (PR65835) which I guess have to do with the compiler checking validity of const char * usage. I don't understand the code well enough to propose a serious patch. -- Tim Prince
